Abstract

The invention relates to a vacuum valve (1) for the gas-tight closing of a flow path (F), comprising a closure disc (5) in which at least one rod recess (6) is formed, and at least one connecting rod (8). The closure disc (5) is removably mounted on the connecting rod (8) by positioning of the rod recess (6) on a connecting section (9) of the connecting rod (8) by means of a screw (16) which is led through a transverse bore (15) in the connecting section (9) and engages a threaded bore (14) in the rod recess (6). According to the invention, a projection (17) and a recess (18) are provided in the connecting region of the rod recess (6) and of the connecting section (9), the projection (17) and the recess (18) being formed in such a way that the projection (17) is gripped round by the recess (18) in a plane containing the connecting rod axis (19), and the closure disc (5) and the connecting rod (8) are fixed to one another in an interlocking manner in the directions of the displacement path (11). The invention makes it possible, after the initial firm tightening of the screw (16), to achieve self-orientation of the closure disc (5) relative to the connecting rods (8) in the directions of the displacement path (11) and to avoid relative movements between the valve disc (5) and the connecting rods (8) during operation.
